Frequently asked questions

Is the shunt resistor installed in the isolation amplifier?

No, the shunt voltage is tapped directly on the shunt and directed to the input of the shunt isolation amplifier. The input areas of our shunt isolator are aligned with the commercial shunt voltages.

Strong currents to be measured are directed via shunt resistors in order to measure the drop in voltage there. The comparatively low voltage at the shunt is tapped directly on the shunt and directed to the input of the shunt isolation amplifier using the 4-pole technique (also known as Kelvin connections or Kelvin contacting).
